A glenoid prosthesis including a bearing shell, the reverse side of which has a plurality of anchoring pins which are arranged to one another. At least one anchoring pin has a coupling element, and at least one sleeve with a fitting securable coupling element and an outer anchoring structure is provided in order to selectively enable a cementing in of the anchoring pin or a mechanical hammering in of the pin together with the sleeve which is fixed to it.

Glenoid prosthesis and a modular system with glenoid prostheses

With the invention a mounting system is shown for metallic support shells at implantable joints with pin-like metallic anchoring elements. The anchoring elements have a head which lies on a shoulder of the implant in the axial direction. Between the shoulder and the head there is a circular sealing edge. A contact pressure force is produced on the head by a contact pressure generating screw which is so great that a metallic seal is produced through plastic flow at the scaling edge which is liquid-tight and prevents the intrusion of abraded particles from the inner region of the support shell.
